// Here's the set-up for this test:
// Step 1. (window) set up listeners for main window.
// Step 2. (same-site iframe) loads, creates a database, and sends "same-site iframe loaded" message.
// Step 3. (window) receives "same-site iframe loaded" message and opens cross-site window.
// Step 4. (cross-site iframe) loads, checks if database exists, and sends "cross-site iframe loaded" message.
// Step 5. (window) receives "cross-site iframe loaded" message, asserts that database should not exist, sends "delete database" message.
// Step 6. (same-site iframe) receives "delete database" message, deletes the database, sends "database deleted" message.
// Step 7. (window) receives the "database deleted" and then exits.
